Nice mount! No Curt USA ball to match it.
Still made in USA (so far) and still high quality! Welds are robotic welded, seems are very smooth and all are completed nicely.The fitment into my 2005 Tundra hitch is a bit loose but this seems to be the norm on Toyota trucks/SUVs. They are wider idkw? Some 2" locks are not wide enough for Toyota hitches.It has a nice weighty feel to it and compared to the Reese mount I'm replacing for hight reasons the steel in this Curt is a bit thicker just looking inside at the square tubing thickness.I did not buy a Curt ball for it as all the Curts I could locate are China made and I refuse to buy one not made in USA.All and all this mount is great but Curt lost money and my respect for outsourcing thier balls and it's not the first time from what I read online.Fact is nobody wants nor trusts China quality so stop trying to shove it down our thoats. -*Thanks all!

Sturdy hitch - don’t forget you need the ball and the right tools to tighten…
I have more than one of these. Strongly consider a version with ball pre-installed if it fits your use case. The tools needed to properly mount the ball of your choosing are not common (e.g. large wrenches and torque wrench that goes to hundreds of ft-lb). I do short occasional trips, but long trips or regularuse definitely should have the ball tightened right or you’ll end up on the news or Facebook.

Muy buen jalón si lo ocupas más reforzado
Este jalón es más reforzado que los más económicos. Para lo que yo lo necesitaba está perfecto, ya que la capacidad es de 4.5 toneladas o 10000 libras.Aparte que el precio no es tan elevado.

Solid and long enough to fit rock guards
Perfect, strong, and long enough to fit the most popular rock taming rock guards.
User
Well built
Very well built. Will serve for moving the trailer short distances as it is much lighter then the equalizer hitch.
